Was thinking the Dollar exchange may be the culprit, BUT looks as though the CDN $ is almost at par with the Aus $.(both worth almost $1.04 USD).......the NZD $ is way off though with $1CDN worth about $1.36 NZD.....I'm sure you would find that just about any products with Corporate Headquarters in NA will result in inflated prices in Oz......also supply / demand for the population.
